Patented May 6, 1930 UNITED STATES PATENT OFFICE ES B.- BBIEDE AND HERMAN L. KUT'IER, 0F HAMILTON, OHIO PAPER-MAKING MACHINE Application filed August 12, 1926. Serial No. 128,810.

This invention relates to paper-making machinery of the type adapted for the formation of a web or continuous sheet of paper from paper stock, and more particularly to that type of paper-making machinery in which an endless paper-making part, such for example as a wire or a belt, is employed in carrying the paper or paper stock.

One of theprincipal objects of the invention is to provide means for stringing the endless paper-making part or wire.

Another object is to provide means for moving one of the paper-making elements, and particularly the suction roll element, out of normal position to facilitate replacement of the endless paper-making part or wire.

Other and further objects of the invention will appear from the following description taken in connection with the accompanying Fig. 1 is a front elevation of a papermaking machine of the Fourdrinier type embodying the present invention;

. Figs. 2 and 3 are enlarged front elevations of the :inlet and the, delivery end of the machine shown in Fig. 1;

Fig. 4 is a vertical end view of the delivery or couchroll end of the machine shown in Figs. 1 and 3, the parts being in normal struction.

operating position; and- Fig. 5 is a view similar to Fig. 4 showing the couch roll moved forwardly out of its normal operating position. y

Referring particularly to Figs. 1, 2 and 3, these figures show the present invention installed in connection with a paper-making machine of the Fourdrinier type, that is, a

machine having a wire 20 which is adapted to receive paper stock from a flow box 21, which latter may be of usual and well-known con- In machines of the type illustrated the wire or screen, which is endless, passes over a breast roll 22 at the inlet end of the machine and over a couch roll 23 at the delivery end of the machine. In passing from the breast roll element 22 to the couch.

ing elements being preferably so constructed and arranged that they may be withdrawn frontwise out of the line of the web of paper in order to permit removal or replacement of the wire. The elements 24 and 25 have supporting carriages 32 extending to the ground and movable thereon so that these elements may be rolled frontwise out of the line of the wire, but the specific construction of the elements-24 and 25 and of the particular form of supporting means illustrated constitute no part of the present invention and are therefore not described or illustrated in detail. Suffice it to say th'atwhen it is desired to remove the table roll element 24 for v the replacement of the wire 20, the breast roll element 22is first removed from its normal position and suspended from the element 24 y the breast roll element is carried forwardly with the table roll element 24, and likewise the guide or tension roll 31 may be suspended in like manner from the opposite end of the table roll element 24 so as to be removed therewith. i

Novel means is herein disclosed for moving I a paper-makin element frontwise out of the line of the endless paper-making part, such means. being illustrated in connection with the couch roll element 23 of the machine, although it should be understood that the invention is not limited in its application to a couch roll element but is applicable to the other elements of the paper-making machine. Referring particularly to F igs. 3, 4 and 5, the paper-making element or couch roll 23 has a movable part or couch roll proper 35 over which the Wire passes during normal operation of the machine, as is well understood. The movable part or roll 35 is mounted for rotation in suitable bearings carried by front and rear carriages 36 and 37 respectively which are so constructed andmounted as to permit the roll 35 to be moved forwardly from'its normal operating position shown in Fig. 4 to the position shown in Fig. 5, or vice versa. The front carriage may be provided with anti-friction rollers 38 adapted to, rollupon a suitable track means 39 laid on the ground or in the foundation of the machine.

Owing to the wei ht ofthe parts it may be desirable to provi e means for positively moving the carriage 36 over its track and for this purpose the track 39 is provided with gear teeth 40 adapted to engage with corresponding gear teeth 41 formed on one of the rollers 38, and such roller 38 may be actuated by any suitable means such as the operating handle 42 which, as hereinshown, has a drivin connection with the gear teeth 41 of the ro ler 38.

The rear carriage 38 is provided with a suspension arm or bracket 45 having a roller bearing 46 adapted to roll upon an elevated track 47, which track is normally supported at its opposite ends upon front and rear supports or pedestals 48 and 49 respectively, which supports have upwardly extending arms 50 connected by a bracing and supporting member 51 which serves as an attachment or support for one end of the wire-stringing means which will be hereinafter more fully described. The front support 48 is provided with an opening 52 of such size as to pass the movable roll 35 and the front carriage 36 when these parts are rolled forwardly as shown in Fig. 5. The rear pedestal or support 49 is provided with a plurality of supporting and guiding rolls 54 normally supporting the rear end of the track 47, but so constructed and arranged as to carry the entire weight of the track 47 when the latter is withdrawn to the rear as illustrated for example in Fig. 5. The lowerrolls 54 are preferably connected with a crank or other suitable'actuating device 55 by which these lower rollers may be rotated in unison to move the track 47 backand forth as desired. The forward end of the track 47 is normally supported by a suitable ledge or shoulder 56 formed in the front support 48.

During normal operation of the papermaking machine the couch roll and associated parts are in-the position illustrated in Fig. 4, it being understood that the wire 20 passes between the roll 35 and track 47 on its upper side and between the roll 35 and the floor or foundation on the lower side. The couch roll is locked in position by means of bolts 57 or other suitable securing means, and it will be'noted that the lower part of the rear carriage is inclined and cooperates with the inclined or wedge-shaped supporting means 58 which latter may be of such height as to raise the roll 46 from the track 47 and to take the weight of the couch roll 35'and of the rear carriage as these parts are moved home to their normal operating position.

Wire-stringing means is provided to facilitate the stringing of the newwire and such means, in the form herein illustrated, comprises an overhead track means which may consist of two spaced apart sup ortin'g cables secured at the rear end of the machine upon the bracing and supporting member 51,

vwhich supporting cables extend forwardly lengthwise of the paper-making machine, passing over the supporting pulleys 72 and being secured to the foundation in any suited to be drawn along the supporting cable, suitable means for drawing the carriage be-' ing provided in the form of a traction cable 75 which may pass forwardly over pulley 71 to asuitable operating device or reel 76, the construction of which is such that the carriage means 74 may be drawn forwardly slowlyfrom its position at the delivery end of the machine as shown in Fig. 3. to the inlet end of the machine as shown in Fig. 1.

- The carriages 74 are each provided with a roll-supportingorv bearing member 77 pivotally connected with the carriage at 78 and normally supported in the position shown in Fig. 3 by means of a latching device 79. The roll-supporting members 77 are constructed in the form of hooks so that when unlatched at 79 the roll-supporting members may swing downwardly about the pivot pins 78 into such position that the roll may be readily placed in the supporting member 77.' The roll-supporting members 77 form bearings for roll caps 80 which, as best shown in Fig. 4, are provided with stub shafts 81 extending therefrom. The new wire screen or wire is commonly rolled upon a roll 82, and when it is desired to support the roll in the carriage preparatory to stringing the new wire, the caps 80 are'placed over the ends of the roll 82 and clamped thereon by any suitable means such as set screws 83. The roll of wire with the caps 80 secured thereon is then placed in the roll-supporting members 7 7 and the latter are swung upwardly and latched in position as indicated in Fig. 3.

, Slidably mounted on the supporting cables 7 0 between the carriages 7 4 and the upwardly extending arms 50 of the couch roll frame are a number of suspenders 85 each of which comprises a stringer tube 86 supported at opposite ends by suspender rods or cables 87 as best shown in Fig. 3. Extending rearwardly from the bracing and supporting member 51 are suspcnder arms 90 upon which is mounted a Suspender 91 comprising, as in the case of the suspenders 85, a stringer tube mal positions and suspended from the tube' roll frame 24, as already described. The tube roll element or frame 24 and the suctionbox frame or element 25 may then be rolled forwardly out of the normal line of movement of the paper and of the wire.

The suction or couch roll element may be moved forwardly out of the line of the paper by first removing the locking bolts 57 and then rolling the movable suction roll part forwardly to the position indicated in Fi 5, the movement of the suction roll being e ected by operation of the operating lever 42. After the suction roll is thus moved forwardly the elevated track 47 may be moved rearwardly upon the rear pedestal or support 49 to the position indicated in Fig. 5.

The several elements of the paper-making machine being thus moved forwardly, and the old wire having been removed in any desired manner, the machine is ready for the insertion of the new wire. r The roll of new wirels suspended 1n the carriages 74 (hereinafter referred to cumulatively as a carriage) and the free end thereof is looped and supported by the suspender 91 to form a loop of such size as to receive the suction roll element. The latter is then moved rearwardly into the loop and the suspender rod 92 removed so as to permit the wire to fall into position about the suction roll. The operating device 76 is then operated to draw the carriage forwardl towards the inlet end of the machine as indicated in Fig. 1, during which forward movement of the carriage the wire unrolls from its roll and is strung along the length of the machine. During the unwinding or stringing process the suspenders 85 are distributed 3 I along the length of the machine somewhat as indicated in Fig. 1 so as to support the upper part of the loop or wire at a height suflicient to permit the tube roll and thesuction roll elements 24 and 25 to be rolled back into normal position without striking or damaging the new wire. The suspenders 85 are then disconnected from the wire to permit the latter to take its proper place upon the tube roll andisuction roll elements, and the breast roll 22 and the tension roll 31 return to their normal operating positions.

A return cable 95 may be connected to the carriage 74 to facilitate the return of the latter to the starting position shown in Fig. 3. In the event that undue pressure or resistance is encountered in returning the suction roll to its operating position with the rear end resting on the support 58 recourse may be had to a jack screw (not shown) or other device to assist the operator in positioning the suction roll element. V

Another method of operating the stringing means is to support the wire cloth carriage at the position occupied by the stringer roll 92, and to then carry the wire forwardly towards the breast roll by one or more of the suspenders 85, the wire cloth carriage remaining in position and unwinding to supply the wire as required. According to this method of operation the means 75 for drawing the carriage along the cable may be affixed to the -moving Suspender or may be dispensed with.

From the foregoing it will be apparent that the present invention provides means for quickly renewing or replacing the endless paper-making part or wire of a paper-making machine. Novel means is disclosed for effecting the rapid movement of the suction roll and other paper-making elements out of the path of the endless wire and for thereafter quickly returning such parts to their normal position, and likewise it provides novel means for rapidly stringing the wire without danger of injury or damage thereto.
